FAQ
What is the RI-15KA?It is a black capless R40 iCONIX set containing sixteen standard lug nuts, four locks, and the matching adapters.
Is this set vehicle-specific?No. Selection is based on the wheel stud thread, seat geometry, clearances, and required quantity rather than a broad year-make-model claim.
Which thread size does it use?Every nut in the set uses an M14 x 1.25 internal thread.
Which wheel-seat style is required?The wheel must use a compatible 60-degree conical lug seat. Ball-seat, mag-seat, and washer-seat wheels are not supported.
How many locks are included?The package includes four locking nuts, allowing one lock to be installed at each wheel on a four-wheel vehicle.
Are decorative end caps included?No. This is the capless open-end configuration; compatible M14 aluminum caps are optional and sold separately.
What tools are needed for installation?Use the supplied adapters with a suitable socket and a calibrated torque wrench, following the vehicle and wheel manufacturer's torque specification.
Can these nuts be used with long wheel studs?The capless open end can accommodate longer studs, but thread engagement, stud protrusion, wheel clearance, and adapter access must all be checked before installation.
Installation Instructions
- Confirm all wheel studs are M14 x 1.25 and every wheel uses a 60-degree conical seat with enough bore clearance for the 24 mm nut body.
- Inspect the studs and wheel seats for damage, contamination, cross-threading, or incompatible hardware before removing the existing nuts.
- Install each lug nut by hand for several full turns, placing one locking nut on each wheel and keeping threads clean and dry unless the vehicle or wheel manufacturer specifies otherwise.
- Use the supplied key and adapter to snug the hardware in the wheel manufacturer's crossing sequence without using an impact tool for final tightening.
- Lower the vehicle as required and torque every nut to the verified vehicle and wheel specification with a calibrated torque wrench, then recheck torque after the recommended settling interval.

Finish a wheel project with Project Kics lug hardware, locks, spacers and service accessories. Compare R40 iCONIX, R26, Leggdura and Monolith references by the look and package you want, then match the complete mounting specifications to your wheels and vehicle.Lug Sets, Locks and Finish ChoicesListings distinguish full lug sets, 16-plus-4 lock packages, lock-only sets and single replacement nuts. Compare the complete count, thread, seat and wheel-hole clearance before choosing a finish or cap style. A no-lock set should not be read as including locking hardware, and a single-nut reference does not supply a full wheel set.Caps, Core Nuts and Replacement KeysR40 iCONIX, Monolith and Leggdura service pieces are system-specific. Choose replacement caps, core nuts or drive adapters for the exact hardware family and size already fitted. Lock-key references also identify different codes; matching the brand or appearance alone is insufficient to choose a replacement key.Spacers, Adapters a...
